personally I would want to get forearmed to the neck, facepalmed and take knuckles to the ribs in practice because chances are someones gonna do it in a tournament. I'd rather condition my body to take it during practice and learn how to deal with it instead of getting shocked by it in a tourney. and it's not like the chances of getting injured from it are any higher than from a choke or armbar or leglock.
They can pull whatever the hell they want on me, granted they don't bitch when I do the same to them.
